Apple MacBook 13" white does not start

[kaushal]

Model: Apple MacBook 13" white

I was working on this machine 3 hours back. Thereafter I put the machine on standby mode.

Now when i try to start the laptop, the icon for password does not appear. Instead a mouse curser sign and a circle [like freezing] appears on the screen. So I am not able to start the laptop.

Please help.
